I rescued a clown from my overflow and in the process some crabs got into the plumbing. I had to take things apart to remove them and now the flow is like 60% slower. I tested the water through the plumbing without the stabdpipe and it gushed at full velocity, so it's the standpipe. I cleaned it out and there's nothing I can see. What could this be?
